开关型电压调节系统的双目标优化设计

A Bi-objective Optimization Design for Switching Regulators

针对开关调压系统提出了一种双目标优化设计方法。最优设计结果使开关调节系统的增广ＩＳＥ指标最小以及功率级电路重量最小，并满足所有静态和动态性能要求。系统的所有设计参数由一个优化程序通过计算机一次计算获得，代替原先用两个软件分别设计功率级电路和控制电路。因此新方法更便于应用。计算机寻优计算结果证明本文提出的优化设计方法简便、合理而且有效。

A bi-objective optimization design approach for switching regulators is presented. The optimum design results in a minimum augmented ISE index of the regulator system and a minimum weight of the power stage satisfying all the static and dynamic performance specifications. The design parameters of the whole system can be obtained by a single compu- ter program in one computation run instead of separating the design of the power stage and the control circuit in two softwares. Thus the new technique is easier to use and more efficient. The computation results show that the proposed modeling approach is simple, reasonable,and highly effective.
